• Nicotine’s addictive potential is the same
regardless of whether nicotine is obtained
through NRT or cigarettes.

MYTH #2
MEDICAL REALITY
Cigarettes are far more addictive than
nicotine replacement products, due to
quantity and delivery of nicotine.

•Toxins, are responsible for most of smoking-caused disease.
•NRT is considered a “clean” nicotine delivery
•Major adverse effects from using nicotine gum/patch are rare.
•Some addictive potential.

MYTH #4
MEDICAL REALITY
• This myth likely originated from six highly publicized case
reports in the media in 1992 about individuals who had suffered heart attacks while smoking and using the patch.*
• A subsequent investigation found no evidence of increased
toxicity among smokers using the patch.**

TOBACCO AND ATHEROSCLEROSIS
SEVERAL MECHANISMS:
• Damages the endothelium lining increases
atherosclerotic plaques.
• Lowers HDL.
• Promotes artery vasoconstriction.
• Increases blood pressure.
• Raises oxygen demand and decrease O2 delivery
of the heart muscle(CO).
• Promotes thrombosis.

MYTH #5
MEDICAL REALITY
• It is more dangerous for patients with heart disease
to continue to smoke than to use NRT.
• Cardiac patients who cannot quit using non-
pharmacologic methods should be among those
first considered for NRT and other cessation
medications.

MEDICAL REALITY
Cessation medications are effective.
NRT and Bupropion have each been found to approximately double quit rates.
Varenicline doubles quit rates.

STOP-SMOKING MEDICATIONS ARE NOT EFFECTIVE
IN HELPING PEOPLE QUIT?
• The benefit of NRT is of increasing the initial quit
rates, not preventing relapse.
• Studying relapse rates in smokers several months
after stopping NRT does not constitute the

• Individualize treatment • Less than 10 cigarettes per day = 7 mg patch
• 10 to 15 cigarettes per day = 14 or 21 mg patch
• 15 to 20 cigarettes per day = 21 mg patch
• If high use, = multiple patches
• Always consider at least 2 different pharmacotherapies for better results

DOUBLE NICOTINE THERAPY
ALTHOUGH OFF LABEL:
With each cigarette being 1 mg of nicotine, and thus a pack being 20 mg. A 7 or 14 mg patch is not sufficient to prevent withdrawal.
Thus, if 2 packs or more are consumed it would be logical to require perhaps 40 mg as day as base line quantity of NRT.

•NRT can be used by people who are not yet ready or able to quit.
•NRT may help some smokers take a “cigarette holiday,” or, in some cases, substantially reduce their smoking as an interim, achievable step toward tobacco abstinence.

• Glycerin (VG) and propylene glycol (PG) are the
most common nicotine solvents used in e-cigarettes
(ECs).
• It has been shown that at high temperatures both
VG and PG undergo decomposition to low

carcinogens formaldehyde and acetaldehyde.
• The aim of this study was to evaluate how various
product characteristics, including nicotine solvent

• Electronic cigarettes (“e-cigarettes”) are devices, about the size of a regular cigarette.
• They operate by electronically vaporizing a solution that often contains nicotine, creating a mist which is then inhaled.
• E-cigarettes are available in various flavors and claimed strengths of nicotine cartridges.

A rechargeable battery powers the vaporizer and has an indicator light to show when the device is in use.

•Battery activates the heating element.
•Commonly contain nicotine, do not actually contain tobacco.
•Although some classes of e-cigarettes are marketed as nicotine-free products, even “nicotine-free e-cigarettes” actually do contain at least trace amounts of nicotine.

• Vapor: gaseous state of a substance.
• An aerosol is a suspension of fine particles of liquid,
solid or both in a gas.

• Varying nicotine concentrations in the solution generating the nicotine aerosol (also called e-liquid),
•Varying volumes of solution in the product,
•Different carrier compounds (most commonly propylene glycol with or without glycerol [glycerin]),
• Wide range of additives and flavors, and battery voltage.
•Quality control is variable,*,Design flaws, lack of adequate labeling
•Engineering differences result in variability in how e-cigarettes heat and convert the nicotine solution to an aerosol and consequently the levels of nicotine and other chemicals delivered to users and the air pollution generated by the exhaled aerosol.

LIPOID PNEUMONIA
• Lipoid pneumonia is a rare, primarily chronic inflammatory reaction secondary to the presence of lipid substances in the lungs, with subsequent uptake by alveolar macrophages and accumulation in the interstitium.
• For this patient, the suspected source of her exogenous lipoid pneumonia was recurrent exposure to glycerin-based oils found in e-cigarette nicotine vapor.
• Many of these compounds are carcinogenic and harmful to humans. Vegetable glycerin is often added to the nicotine solutions used in e-cigarettes to make the visual smoke when the solution is vaporized. Glycerin is produced by heating palm or coconut oil; however, it can also be produced from animal fat and soap through a fatty acid splitting operation.

LIPOID PNEUMONIA
• Most cases of exogenous lipoid pneumonia
are associated with aspiration of mineral oil
or lipid-based preparations.

CONCLUSION
• Patients should be advised to stop smoking as
early as possible, but there is no evidence to
suggest that health professionals should not be
advising smokers to quit at any time prior to
surgery.

cigarettes

FACT
• Legacy Tobacco Documents Library
(http://legacy.library.ucsf.edu) show that menthol is
added to cigarettes in part because it is known to
be an attractive feature to inexperienced smokers
who perceive menthol cigarettes as less harsh and
easier to smoke and because of their availability
from friends and family.
Also the tobacco industry found that some youths
smoke menthols because they perceive them to be
less harmful than non-menthol cigarettes.

Diabetes
• The evidence is sufficient to infer that cigarette smoking is a cause of diabetes.
• The risk of developing diabetes is 30–40% higher for active smokers than nonsmokers.
• There is a positive dose-response relationship between the number of cigarettes smoked and the risk of developing diabetes.

Rheumatoid Arthritis
• The evidence is sufficient to infer a causal
relationship between cigarette smoking and
rheumatoid arthritis.
• The evidence is sufficient to infer that cigarette
smoking reduces the effectiveness of the tumor
necrosis factor-alpha (TNF-α) inhibitors.

• In type 2 diabetes, smoking cessation is associated
with deterioration in glycemic control that lasts for 3
years and is unrelated to weight gain.
• At a population level, this temporary rise could
increase microvascular complications.
